Performance Bikes (UK) - - Project Bike -

HONDA RAC­ING GAVE us an ex­clu­sive look at the dyno charts for their bikes, and ran our project bike on their dyno for com­par­i­son. The or­ange line is our bike: fairly typ­i­cal for a stan­dard, pre-2014 model with­out the fet­tled head and fac­tory blueprint­ing. “It’s vi­brat­ing a a bit, though, they’re usu­ally smoother than this,” Paul no­ticed. That’ll be the bol­locksed chain and miss­ing en­gine mount. Don’t you worry about that…

In blue is the stan­dard Fire­blade SP O’Hal­lo­ran’s 2014 Su­per­stock bike was built from. The gains from the fet­tled head are well worth us in­ves­ti­gat­ing fur­ther when we have our mo­tor out for the thread re­pair. Next up is the same bike, but fit­ted with an Akrapovic race ex­haust plus a Baz­zaz fuel in­jec­tion mod­ule – Su­per­stock rules only al­low plug-in fu­elling/ ig­ni­tion man­age­ment. There’s a small gain at the top, but the grunt is most im­pres­sive – up to 9000rpm it’s the strong­est bike here, by around 15bhp at cer­tain revs!

The BSB bike is nat­u­rally the most pow­er­ful, and lin­ear, with sub-Su­per­stock midrange build­ing to a 200bhp-plus top end. “The curve is that shape to make it eas­ier to drive – we could have the low-rev torque of the stock en­gine, but with the cur­rent ca­ble-op­er­ated in­jec­tion, it makes it harder to get out of cor­ners. With the new bike’s ride-by-wire, we can to put the power back, and man­age it, too.
